matplotlib.patches.FancyBboxPatch

class matplotlib.patches.FancyBboxPatch(xy, width, height, boxstyle='round', bbox_transmuter=None, mutation_scale=1.0, mutation_aspect=None, **kwargs)

Bases: matplotlib.patches.Patch

A fancy box around a rectangle with lower left at xy = (x, y) with specified width and height.

FancyBboxPatch is similar to Rectangle, but it draws a fancy box around the rectangle. The transformation of the rectangle box to the fancy box is delegated to the BoxTransmuterBase and its derived classes.

Parameters:

xy : float, float

The lower left corner of the box.

width : float

The width of the box.

height : float

The height of the box.

boxstyle : str or matplotlib.patches.BoxStyle

The style of the fancy box. This can either be a BoxStyle instance or a string of the style name and optionally comma seprarated attributes (e.g. "Round, pad=0.2"). This string is passed to BoxStyle to construct a BoxStyle object. See there for a full documentation.

The following box styles are available:

Class	Name	Attrs
Circle	circle	pad=0.3
DArrow	darrow	pad=0.3
LArrow	larrow	pad=0.3
RArrow	rarrow	pad=0.3
Round	round	pad=0.3, rounding_size=None
Round4	round4	pad=0.3, rounding_size=None
Roundtooth	roundtooth	pad=0.3, tooth_size=None
Sawtooth	sawtooth	pad=0.3, tooth_size=None
Square	square	pad=0.3

mutation_scale : float, optional, default: 1

Scaling factor applied to the attributes of the box style (e.g. pad or rounding_size).

mutation_aspect : float, optional

The height of the rectangle will be squeezed by this value before the mutation and the mutated box will be stretched by the inverse of it. For example, this allows different horizontal and vertical padding.

get_bbox(self)

Return the Bbox of the rectangle.

get_boxstyle(self)

Return the boxstyle object.

get_height(self)

Return the height of the rectangle.

get_mutation_aspect(self)

Return the aspect ratio of the bbox mutation.

get_mutation_scale(self)

Return the mutation scale.

get_path(self)

Return the mutated path of the rectangle.

get_width(self)

Return the width of the rectangle.

get_x(self)

Return the left coord of the rectangle.

get_y(self)

Return the bottom coord of the rectangle.

set_bounds(self, *args)

Set the bounds of the rectangle.

Call signatures:

set_bounds(left, bottom, width, height)
set_bounds((left, bottom, width, height))

Parameters:

left, bottom : float

The coordinates of the bottom left corner of the rectangle.

width, height : float

The width/height of the rectangle.

set_boxstyle(self, boxstyle=None, **kw)

Set the box style.

boxstyle can be a string with boxstyle name with optional comma-separated attributes. Alternatively, the attrs can be provided as keywords:

set_boxstyle("round,pad=0.2")
set_boxstyle("round", pad=0.2)

Old attrs simply are forgotten.

Without argument (or with boxstyle = None), it returns available box styles.

The following boxstyles are available:

Class	Name	Attrs
Circle	circle	pad=0.3
DArrow	darrow	pad=0.3
LArrow	larrow	pad=0.3
RArrow	rarrow	pad=0.3
Round	round	pad=0.3, rounding_size=None
Round4	round4	pad=0.3, rounding_size=None
Roundtooth	roundtooth	pad=0.3, tooth_size=None
Sawtooth	sawtooth	pad=0.3, tooth_size=None
Square	square	pad=0.3

ACCEPTS: [ 'circle' | 'darrow' | 'larrow' | 'rarrow' | 'round' | 'round4' | 'roundtooth' | 'sawtooth' | 'square' ]

set_height(self, h)

Set the rectangle height.

Parameters:

h : float

set_mutation_aspect(self, aspect)

Set the aspect ratio of the bbox mutation.

Parameters:

aspect : float

set_mutation_scale(self, scale)

Set the mutation scale.

Parameters:

scale : float

set_width(self, w)

Set the rectangle width.

Parameters:

w : float

set_x(self, x)

Set the left coord of the rectangle.

Parameters:

x : float

set_y(self, y)

Set the bottom coord of the rectangle.

Parameters:

y : float
